Question 1

What does error code F1 mean on Samsung RF221NCTAWW?

Accepted Answer

Refrigerator cannot sense the room temperature. Cause: Potential causes include separation in sensor housing, contact errors at connectors, disconnection of sensor wires, short circuits within the sensor line, or temperature readings exceeding 149°F or dropping below -58°F..

Question 2

What does error code F2 mean on Samsung RF221NCTAWW?

Accepted Answer

Freezer section temperature sensor is not responding. Cause: Possible causes include separation of the sensor housing, contact error at the connector, disconnection of the sensor wire, short circuit in the sensor line, or an out-of-range temperature reading..

Question 3

What does error code F3 mean on Samsung RF221NCTAWW?

Accepted Answer

Defrost system cannot monitor freezer coil temperature. Cause: Causes may include separation in sensor housing, contact errors at connectors, disconnection of sensor wires, short circuits within the sensor line, or temperature readings exceeding 149°F or falling below -58°F..

Question 4

What does error code F4 mean on Samsung RF221NCTAWW?

Accepted Answer

Freezer section is not getting circulation air flow. Cause: Potential issues include an error in the fan motor's feedback signal line contact, separation within the wiring, mechanical failure of the motor, seized bearings, or obstruction/jamming of the fan blade..

Question 5

What does error code F5 mean on Samsung RF221NCTAWW?

Accepted Answer

Fresh food compartment is not getting enough cold air circulation. Cause: Potential causes include an error in the fan motor feedback signal line contact, wiring separation or breakage, mechanical failure of the fan motor, bearing failure within the motor, or obstruction of the fan blade..

Question 6

What does error code F6 mean on Samsung RF221NCTAWW?

Accepted Answer

Humidity monitoring system is not working. Cause: Possible causes include moisture damage to the sensor, a short circuit in the sensor line, disconnection of the sensor wire, contact error at the connector, or separation of the sensor housing..

Question 7

What does error code F7 mean on Samsung RF221NCTAWW?

Accepted Answer

Freezer defrost heater is not functioning or overheating. Cause: Possible causes include defrost heater housing separation, contact error at the heater connector, disconnection in heater wiring, short circuit within the heater element, temperature fuse failure, or an incomplete defrost cycle with heating exceeding 80 minutes..

Question 8

What does error code R1 mean on Samsung RF221NCTAWW?

Accepted Answer

Ice maker temperature sensor is not working properly. Cause: Potential causes include separation in sensor housing, contact errors at connectors, disconnected sensor wiring, short circuits within the sensor line, or temperature readings outside the range of -58°F to 149°F..

Question 9

What does error code R3 mean on Samsung RF221NCTAWW?

Accepted Answer

Refrigerator compressor will not operate or is operating abnormally. Cause: Start-up fails when there is a short circuit between compressor terminals, a short between IPM (Intelligent Power Module) pins, an IPM module fault, abnormal current, motor restriction or locked rotor, excessive RPM, shunt resistance failure, low input voltage, or over voltage..

Question 10

What does error code R4 mean on Samsung RF221NCTAWW?

Accepted Answer

Fresh food compartment temperature sensor is malfunctioning. Cause: Possible causes include separation in sensor housing, contact errors at connectors, disconnection of sensor wires, short circuits within sensor lines, or temperature readings outside the range of -58°F to 149°F..
